Betrothed of Fire rulings:
2008-04-01: If you control Betrothed of Fire, but it’s attached to a creature you don’t control, no one can activate the last ability. The creature’s controller can’t activate it because that player doesn’t control the Aura. You can’t activate it because you can’t pay the cost — you can’t sacrifice a creature you don’t control.
